Team 5 Investigates' Kathy Curran learned much more about the two suspects within the past 24 hours. The massive manhunt for Dzhokhar Tsarnaev, 19, continues.

He's the suspect identified by the FBI in the white hat. He grew up on Norfolk Street in Cambridge and went to the Cambridge Community Charter School. He graduated from Cambridge Rindge and Latin in 2011. Tsarnaev was a wrestler and an all star in 2011 for his high school team. He was awarded a scholarship by the city of Cambridge.

He was also a student at the University of Massachusetts-Dartmouth, which was evacuated on Friday.

Former classmates told Team 5 he was a sweet, popular kid, but now he is a wanted man.

His older brother, Tamerlan Tsarnaev, was the suspect pictured in FBI photos and surveillance video wearing a black hat.

Early Friday morning, the 26-year-old was shot by Watertown police in a gun fight and sustained multiple gun shot wounds and what appeared to be blast wounds and trauma. He was then run over by his younger brother who was fleeing the scene. He was pronounced dead at 1:35 a.m at Beth Israel Hospital.

The older Tsarnaev spent three semesters at Bunker Hill Community College. A spokesperson for the college tells us he was studying accounting and last attended in 2008.

Team 5 has also learned Tsarnaev was a champion boxer who wanted to compete in the Olympics for the United States. ABC news spoke to his father who said Tamerlan has a 3-year-old daughter and has lived in Massachusetts for 10 years.

Law enforcement sources told Team 5 the suspects told the carjacking victim in Cambridge they did the Boston bombings, that they just killed a cop and they told the victim "if you don't give us your car we'll kill you."
